Role of Modified Biophysical Profile and Doppler Velocimetry in Timing of Pregnancy Termination in Growth Restricted Fetuses after 32 weeks of Gestation.
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 11
Abstract
AIM: To optimize the timing of pregnancy in growth restricted fetuses in pregnant women after 32wks of gestation by using modified biophysical profile & Doppler velocitometry. Objectives: To estimate the relevance of MBPP & Doppler velocitometry in deciding the mode of delivery and to measure the lag time between abnormal Doppler finding and MBPP. Methods: Hospital based observational study done on 100 patients in the department of obstetrics & gynecology in collaboration with department of radiology, Gandhi hospital from the period of January 2015 - November 2016. Results: In group with abnormal Doppler presentation there was increased incidence of caesarean section and adverse perinatal outcome. In analysis of perinatal outcome the sensitivity and specificity of abnormal umbilical artery Doppler was 76% & 64% respectively. Conclusions: 1) Abnormal Doppler had sensitivity of 53.3%, specificity of 51.76%in predicting fetal distress. 2) Abnormal MBPP had sensitivity of 100% and specificity of 50.2% and negative predictive value of 100% in predicting fetal distress. 3)Combined abnormality of both Doppler & MBPP had sensitivity of 100%, specificity of 52% negative predictive value of 100% in predicting fetal distress. The fetal compromise was greater when both Doppler & MBPP were abnormal. 4) Abnormalities in Doppler preceded on abnormal MBPP by lead time of 7.12 days which is important in the management of preterm high risk pregnancies.
